Analog Output in case of actuator with 0-20mA(4-20mA) usage. This actuator can control a fuel rack for diesel engines or a mixture throttle valve for gas engines. ECON-4 ADV is advanced version, it is dedicated specially to control of engine in island operations where load steps are expected.
Power supply fusing An eight-amp fuse should be connected in-line with the battery positive terminal to the controller and modules. ECON-4 should never be connected directly to the starting battery. Recommended fuse is slow type – T8A. Grounding Use as short as possible cable to the grounding point on the switchboard Use cable min.
Binary inputs Binary inputs have internal load resistor 4.4 kΩ connected to the battery plus. Binary inputs are used to control the function of the ECON-4 digital governor. Binary inputs can be read from: • the physical Binary inputs (terminals S4.x), •...
Load gain, Load int, Load der Load control according Speed/Fuel Line Note: There is more Load gain, Load int and Load der values in ECON-4 ADV. Which set will be used depends on actuall power. See description on page 51. S4.3 NOMINAL The Required speed is set to Nominal RPM if the Nominal input is closed, otherwise is the Request set to Idle RPM.
Analog inputs There are 2 analog inputs available on the ECON-4. Each of them can be configured either as 0-20mA or 0-10V range by jumper setting – see in table below. The analog input function is fixed.
Principle of connection Master Slave is shown on next picture. Analog outputs ECON-4 has one analog output configurable to 0-10V or 0-20mA range by jumper setting – see in table below. If configured to 0-20mA range, output works as an active current source. The analog output function is fix (copy of the value sent to ACT output).
P6 adjusted to voltage option. Interface to actuators ECON-4 has one interface to actuator. The interface has a bipolar PWM output in bridge configuration and position feedback input. It is recommended to connect PWM output by a twisted cable and connect feedback input by a shielded cable.
CAN bus connection ECON-4 is equipped by CAN communication line. CAN bus terminals are electrically isolated from any other terminals. Hint: Following ECON-4 CAN setting is necessary to communicate with InteliSys NT: - CAN mode (Object number 10338) = 1 sets ComAp protocol...
Quick start – how to set ECON4 and controller The following description should help you to quick adjust the ECON-4 speed governor. The ECON-4 can be found in different modes used for control of module and engine. Basically any input signal of ECON4 can be supplied either using wired signal or using data from CAN1 line.
Page 19
In case of BINary control, the ECON-4 is fully controlled via binary inputs – terminals S4.3 – S4.8.(except CB control). The input S4.6 is the ON/OFF signal to ECON-4, in case it is not active, speed governor will not open the throttle. In case it is deactivated during engine running, throttle is immediately closed.

Speed request set to DATA mode In case of DATA control almost all the data can be sent from ComAp IGS-NT controllers to ECON-4 via CAN1 line. The only binary input RUN/STOP – S4.6 must be activated physically as well. To use the DATA mode, adjust the IGS-NT inputs/outputs in the following way: a.

ECON-4 is equipped with the Load anticipation function to react as quickly as possible to the sudden changes of the engine power. For this function ECON-4 needs information about power and in case of DATA mode this can be sent to ECON-4 via CAN. Adjust the AOUT1 in the following way:...

Idle, Nominal, Overspeed RPM: Engine RPM: Idle RPM, Nominal RPM, Overspeed. WARNING: Please, take in account, there are several setpoints of ECON-4, which are not accessible via IGS-NT control unit in case of DATA mode. These parameters are crucial for ECON-4 and used Actuator adjustment and so these are accessible via ECON-4 connection ONLY.

Run/Stop Droop The physical RUN/STOP – S5.6 binary input must be closed in any type of control to run ECON-4 i.e. in “DATA mode” together with data command BO4 Run/Stop to enable speed control function (unblock the actuator from 0% position).

750mA. In case the maximum allowable actuator current is 250mA, then this is 33.3% of maximum ECON-4 current. Adjust Act Cur 0% to 0% and Act Cur 100% to 34% (250mA from 750mA). By this the output is scaled from 0 to 250 mA.

2,5 Ohms and power supply is 24V, then maximum ECON-4 current is: 24/2.5 = 9,6A but ECON max allowable current is 8 Amps!! So the output must be limited. This means 100% of ECON theoretical current is 9,6A. In case the maximum allowable actuator current is 5A, then this is 52% of maximum ECON-4 theoretical current.

Connect the actuator to ECON-4, outputs ACT+ ACT- (take care about polarity!!) J. Adjust ECON-4 parameter: Main PID: ECON-4 mode to MANUAL and run WinScope recording with values: Gas Dose and Act1 Fdbck in range 0.0 – 100.0%. K. When recording is active, change parameter: Main PID: Act position from 0 to 10, 20, 30, ..
Getting started, programming Connection to ECON-4 Connect RS232 cable and start WinScope software. Click on the Connection, Open Connection and choose Direct connection type, EmCon5, ECON-4, INCON Controller type, choose the right COM port and press O.K. button. Setpoints adjustment: Click on the icon Setpoints to open the Setpoints groups.
Block schematics – speed governor Speed governor function in Idle or local load mode ECON-4 compares the Reference and Actual speeds of the engine and calculates the Regulation error. The Actual speed is measured from the period of the signal generated by the magnetic pickup sensing gears of the flywheel.
1 RPM Range: 0 – 2500 RPM Overspeed [RPM] Maximum acceptable speed of the engine. If the actual engine speed is higher, ECON-4 immediately closes the actuator. Normal function is restored after detection of zero engine speed. Step: 1 RPM Range: 0 –...
1-50% Engine Start ECON-4 activates the start sequence if it detects non-zero engine speed and if input RUN is active. Actuator is set to position InitStart dose. Actuator then gradually increases fuel dose till the engine start or till it reaches MaxStart dose. The speed of fuel ramp is defined by setpoint Fuel ramp time.
0 – Idle RPM Hint: ECON-4 can work only if Starting RPM < Idle RPM < Nominal RPM. If this condition is not met, ECON- 4 activates bit Invalid setpoints in Transmit PDO 1, see description of CAN protocol. It is not possible to run the engine if the bit Invalid setpoint is signalized.

Load anticip Governor is equipped by load anticipation feedback, which helps to keep stable speed in case of fast load changes. In the case of load jump forces the ECON-4 governor output (Actuator lever) by jump according to Load anticip setting.

ECON-4 must be in AUTO for normal operation. Mode MAN can be used during installation to check the function of the actuator and linkage. If ECON-4 is in MAN mode, it sets the actuator to position Act position. It can be switched to MAN mode only any time even engine is running. This allows measurement of transition curve to calculate PID parameters.
Act position Adjusts the actuator position in the Econ-4 Mode = MAN. Step: 0.1 % Range: 0.0 – 100.0 % PWM rate [Hz] Frequency of the PWM signal sent to ACT+ and ACT- outputs. Step Range 600 – 10 000 Hz For Heinzmann actuators adjust the PWM rate to 6000 Hz.

Fdb 0 pos Feedback fully closed position voltage. Connect the position feedback to the ECON-4 terminals. Keep the actuator lever in fully closed position and measure a dc voltage between the terminals S2.1 and S2.3.
Fdb1 0 pos – 4,60 V ActType 1, 2, 3, 4 There are four identical groups of setpoints in ECON-4. They are used to setup the output circuits for particular types of actuators and tune the actuator position PID loop.
